Polybutylene Service and Valve Replacements (CI 5688 & CI 5689)

The Polybutylene Service and Valve Replacements project (CI 5688 & CI 5689) is a forecast infrastructure initiative by the City of Thousand Oaks, California, under NAICS code 237110. The project aims to enhance water system reliability by replacing 125 existing polybutylene water service lines, which are susceptible to chlorine degradation and microfracturing, with durable copper tubing. The scope of work also includes the installation of 125 cathodic protection systems and the removal and reinstallation of 54 valves. The work will be performed within the public right of way in Thousand Oaks, Ventura County, and is classified as a Class 2(c) improvement under the California Environmental Quality Act. Technical requirements include minor trenching through paved surfaces, with a mandate that all excavations be backfilled and restored to their original condition. Contractors must adhere to standard trenching and excavation practices, specifically regarding sheeting, shoring, and compliance with public safety and roadway restoration requirements. The project is administered by the City Engineer, Ted Gerber, with Chandani Gunasekara serving as the primary point of contact.
